[NTLUG:Discuss] RedHat 6.1/KDE installation

[saluki@hex.net]

Has anyone else had problems with a clean install of RedHat6.1 and KDE, of 
having all thier applications comeback with the error of :

XLib : cannot connect to server :0.0 

or something very similar to this? I remember seeing this back when I first 
installed 6.1, but its been so long ago, I can't remember what I did to fix it, 
or where to find the fix. I've checked out kde.org and couldn't find it, and 
redhat.com is pretty much all 6.2 and 7.0 nowadays....

Anyone else have an idea? 

Thanks!
Don
